In this video we continue our exploration of the M25... perhaps the most notorious motorway in all of the UK. It surrounds London and was the left overs of a failed road building project leading to some interesting choices and decisions. It seems to do everything wrong and I don't think there are many that have a good word to say about the M25 but it's the only motorway left so I've no option but to tackle this giant. In this weeks episode we pick up the M25 in Hertfordshire and follow it to it's end in Essex.. it's the final episode of a series that's been going for over a year and a half, 80 videos later it's time to visit the motorway for the last time. I can't thank you enough for coming along on the journey, I hope you liked the series. In this series I aim to explore what our motorway network is hiding. As we drive along at 70mph..ish...we simply just wouldn't be aware of what we're missing. This series will uncover some of the hidden secrets our motorways have to offer.
